Clothes normally change color after fading. But you know that there are dyes that change the color of clothes after exposure to sunlight.
Photochromic dyes create a dramatic effect on clothes and cause them to change color when the clothes are exposed to sunlight and absorb ultraviolet radiation. Once the radiation is removed, the clothing returns to its original color. (See this video for more.)
Depending on the environment, day or night, sunlight or shade, the clothes change color.
Technology:
These photochromic dyes generate a dynamic reversible color change under sunlight or ultraviolet (UV) light.
They can be applied to fabrics through conventional methods of printing, dyeing, spraying, etc.
Despite the amazing effects, these types of coatings are not yet commercially successful. The water-insoluble nature of photochromic dyes makes application to wool or cotton impossible.
In addition, these dyes do not have the capacity to withstand heat, causing clothing to be damaged quickly.
However, photochromic colors may create a new trend in the fashion industry. It will be of great help to garment manufacturers by providing new marketing opportunities. Clothing with changing motifs, letters and patterns that are visible in sunlight and fade in shade could create a revolution in the clothing industry.
